Our first stop on our Peak to Peak highway drive on Sunday was Mary’s Lake. Hardly any breeze so the lake was smooth as glass. Every plant still in the shade, had a coat of light frost on it. Marys Lake is part of the Colorado-Big Thompson Project. There are 2 dikes on the shoreline of Mary’s Lake, located approximately 2 miles from Estes Park, Colorado. Mary’s Lake serves two primary purposes: it acts as an afterbay for the Mary’s Lake Power Plant, and it helps regulate Colorado-Big Thompson Project water on its way to the Estes Power Plant. I guess another purpose is to provide beautiful reflections.
